Intraspecific crosses resulting in the first occurrence of eight and nine B chromosomes in Prochilodus lineatus (Characiformes, Prochilodontidae)

B chromosomes are supernumerary elements present in about 15% of eukaryotic species and are most frequently heterochromatic, behave parasitically, show a transmission rate higher than standard (A) chromosomes, and can provoke harmful effects on carriers. In the current work, Prochilodus lineatus individuals carrying eight and nine B chromosomes were obtained by induced crossing performed involving breeders with different B chromosome numbers in their cells. The high B chromosome numbers found in the offspring were recorded for the first time in this species. The use of cytogenetic techniques applied in the present study revealed that regardless of the increase in number of B chromosomes in the genome of these individuals, those elements did not presented active genes, and showed their normal heterochromatic characteristic

Avaliação de Programas de Controle de Infecção relacionada a Assistência à Saúde de Hospitais

RESUMO Objetivo Avaliar os Programas de Controle de Infecção em hospitais do Paraná, considerando como hipótese desempenho geral mínimo de 75%. Método Estudo transversal de avaliação processual, por meio de instrumento previamente validado, composto por quatro indicadores que avaliam a estrutura técnico-operacional (PCET), as diretrizes operacionais (PCDO), o sistema de vigilância epidemiológica (PCVE) e as atividades de controle e prevenção (PCCP). O estudo foi realizado de 2013 a 2014 em 50 hospitais por amostra de acesso. Resultados A conformidade geral obtida foi 71,0% (23,88dp), sendo indicador PCET 79,4% (18,9dp); PCVE 76,0% (30,5dp); PCDO 65,5% (26,9dp); e PCCP 63,2%/ (39,5dp). Houve significância estatística para melhor desempenho dos PCIRAS a realização de auditorias internas (p=0,0099), certificação de qualidade (p=0,01949), enfermeiro exclusivo (p<0,0001), profissionais médicos contratados ou concursados (p=0,0005), maior carga horária de dedicação exclusiva dos médicos, 4 horas (p=0,001), maior tempo de experiência de médicos (p=0,0028) e enfermeiros (p=0,0094). Conclusão A conformidade geral desses programas não alcançou a hipótese inicialmente formulada, devido aos indicadores PCDO e PCCP. Desse modo, é possível considerar que os programas apresentavam adequação mínima para sua operacionalização e para realizar a vigilância epidemiológica de IRAS, mas estavam prejudicados quanto à insuficiência quantitativa e qualitativa de diretrizes operacionais (PCDO) e de ações para o controle e prevenção dessas infecções (PCCP)

Low haemoglobin levels increase unilateral spatial neglect in acute phase of stroke

Objective The objective of this study was to evaluate the relationship between unilateral spatial neglect (USN) and haemoglobin (Hb) level in acute phase of stroke. Method Cross-sectional study was performed after right hemisphere ischemic stroke. Independent variable: Hb level (mg/dL); Outcome: USN; Potential confounding factors: Age, National Institutes of Health Stroke Scale (NIHSS), and glycaemia (mg/dL); Characterization variables were obtained from electronic medical records, Hb, mean corpuscular volume (MCV) and glycaemia by laboratory exams, and USN by cancellation and bisection tasks. The relationship between Hb and USN was assessed by Spearman correlation and linear regression model. Results 40 individuals were evaluated; it was observed that the higher the Hb level, the better the USN test performance, with the two being negatively correlated. There was no significant correlation between VCM level and USN performance. Conclusion Low hemoglobin levels may indicate a worse performance in USN cancellation and bissection tests in acute phase of stroke
